Q: Issues when stopping volume

Another issue popped up while I was trying to troubleshoot XSAN. I went to stop the volume so that I could run CVFSCK to check the volume. I thought that the Volume Stopped, but it seems that the computer still thinks its mounted. It shows up when I do a ls in /Volumes but when I try to enter the volume it stalls. Also when I tried to logout of the computer, it just hung. It seems like Finder crashed and is preventing the computer to logout. Now I can't even restart it. I'm afraid to force a shutdown in fear of possibly corrupting the XSAN volume.

Below is from system.log right after I attempted to stop the volume.
